of all JavaBeansTM
has been added to the java.beans package.

Constants
public static final int ANCESTOR_ADDED
An ancestor-component was added to the hierarchy of visible objects (made visible), and is currently being displayed.
public static final int ANCESTOR_MOVED
An ancestor-component changed its position on the screen.
public static final int ANCESTOR_REMOVED
An ancestor-component was removed from the hierarchy of visible objects (hidden) and is no longer being displayed.
Public Constructors
public AncestorEvent (JComponent source, int id, Container ancestor, Container ancestorParent)
Constructs an AncestorEvent object to identify a change in an ancestor-component's display-status.
Parameters
| source | the JComponent that originated the event
(typically this) |
|---|---|
| id | an int specifying ANCESTOR_ADDED,
ANCESTOR_REMOVED or ANCESTOR_MOVED |
| ancestor | a Container object specifying the ancestor-component whose display-status changed |
| ancestorParent | a Container object specifying the ancestor's parent |
Public Methods
public Container getAncestorParent ()
Returns the parent of the ancestor the event actually occurred on. This is most interesting in an ANCESTOR_REMOVED event, as the ancestor may no longer be in the component hierarchy.
